M5Stack 4IN8OUT Multi-channel DC Drive Module (STM32F030)

The 4IN8OUT Multi-channel DC Drive Module from M5Stack is a 4-Channel Passive Input/Switch + 8-Channel MOS Drive Output drive module. The module adopts STM32F030 as the I2C IO chip and supports 9-24V DC input, with internal DC-DC circuitry to 5V. Features

* Compatible with Basic/Fire/Core2

* Adopt STM32F030 as the IO chip, I2C communication, I2C address is changeable by modifying the register

* 8-channel MOS Drive circuitry shares the same VCC, channel load <1A

* 4-channel Passive Input share the same GND, no active signal or >5V signal allowed

* With internal MP1584, 9~24V -> 5V DC-DC converter
